In his first-ever interview, the sole Australian survivor of the Waco siege has revealed to 60 Minutes what really took place during the 51-day stand-off, and why he believes crazed cult leader David Koresh will one day return to Earth as the son of God.

Where's summer? Cold weather and storms threatening fun in the sun

If you've been scratching your head wondering what happened to summer, you're not alone. While many Australians are ready to bust out the thongs, singlets and wide-brimmed hats, Mother Nature hasn't quite delivered the goods yet.

Sydney is yet to crack past 30 degrees this season, Melbourne's copped its coldest start to summer in 16 years and a winter-like cold snap in western Queensland has left residents shaking their heads at record low temperatures.

The good folk of Adelaide have been dealt their coldest start to summer in almost half a century, leaving the Poms feeling more at home than the Aussies at this week's Adelaide Oval test match.

Storms have also been common – with severe weather bringing the risk of large hail and damaging winds to south-east Queensland today, with Brisbane in line for more storms and possibly dangerous conditions this afternoon.

Sydney, too, is not immune from the storms, with fiery skies expected this afternoon, especially in the western suburbs. The risk of severe storms will continue in south-east Queensland and northern New South Wales across the weekend.

And then there's the rain. Melbourne collected yet another drenching overnight, with some eastern suburbs receiving another month's worth of rain in 24 hours.

But don't be fooled by the cool start. Climatologists at the Bureau of Meteorology say Melbourne, Adelaide and Hobart are on track to receive above average temperatures for the rest of December.

"It might feel cool now, but don't think that that's how the rest of summer is going to be," long range forecaster Dr Andrew Watkins warns.

Almost as if on cue, most Australian capital cities are expecting a rise in temperatures in the next five days.

In Sydney, the warming trend begins this weekend. The showers and storms will clear overnight, and while temperatures will hover in the mid-twenties tomorrow, they'll rise steadily from Sunday.

Sunny skies will greet your Sunday morning as a sign of things to come, before temperatures climb each day next week. By Wednesday, the city should finally crack past 30 degrees for the first time this summer.

Now I'm just going to go out on a limb here and say that most Aussies would consider proper summer temperatures to be numbers that start with a "3". Once we reach the 30s, we're in business.

Melbourne can expect to register on the 'summer-meter' soon. After a cloudy day tomorrow, temperatures will gradually rise from Sunday.

By Tuesday, the city will hit the low 30s and remain there until at least Thursday. There is also reprieve from the rain, with dry conditions expected from Saturday through to Thursday.

Adelaide will get a taste of summer from Monday, when temperatures hit the low thirties. The temperature will remain above 30 degrees until at least Thursday. In the meantime, the city has also been dealt a pretty sweet weekend. The mercury will be in the mid-20s tomorrow before climbing to the high 20s on Sunday. That's good news for the 40,000 people who are expected to gather in Civic Park for Australia's second-biggest Christmas Carols event that night.

Canberra is also following suit, with a gorgeous weekend in store. Mostly sunny conditions tomorrow will trigger a warming trend that will take Canberra all the way up into the mid-30s by Thursday.

The forecast is not quite as welcoming in Brisbane, where residents are still contending with storms and showers. The rumbles and rain are set to continue through the weekend, with storms possible tomorrow and leftover showers on Sunday. But the middle of next week should bring dry weather, and gorgeous temperatures in the low-30s to go with it. So hang in there Brissie!

Darwin residents are probably wondering what all the fuss is about, with temperatures in the mid-30s well and truly the norm now. The usual summer storms and sweaty weather will continue in Darwin for as long as any forecast will care to mention.

In fact, if we were handing out a medal for the summer stakes this season, that medal would have to go to Perth. The city has been sitting in a summer sweet spot all month, and temperatures will remain in the 30s across the weekend. There's the odd chance of a storm come Sunday, but for the most part Perth, you are in the clear and ready to roll out those beach towels, if you haven't done so already.

So as another day of below average temperatures rolls out across much of Australia today, the message is clear: be patient. It might feel cool now, but summer will kick in and you'll be rubbing aloe vera on your sun-smacked shoulders while comparing singlet tan lines in no time.
